Optimising treatment (TDM)

Optimising treatment (Biomarkers)

Therapeutic Drug Monitoring (TDM) and biomarkers such as faecal calprotection (FC) can be useful tools in helping to support clinical decision making to optimsie treatment. Treatment optimisation can involve changing the dosing, infusion interval or stopping treatment. 

Please note that Inflectra/infliximab is not licensed for dose escalation in ulcerative colitis, ankylosing spondylitis, psoriasis, psoriatic arthritis, paediatric ulcerative colitis or paediatric Crohn's disease.

What is Faecal Calprotectin?

Faecal calprotectin (FC) is a biomarker of disease activity in IBD.

FC correlates with inflammatory activity in CD and UC.1 

It is stable in stool for up to 3 days at room temperature so it is readily mesaurable.2 

FC levels can be used to:

  • Confirm active disease (when clinical symptoms are present)3
  • Evaluate efficacy of current thearpy (mucosal healing)4
  • Predict disease course5
  • Stratify treatment (modulating disease course)6
